Before the selection, we first need to understand the basic parameters of the circuit, including the rated voltage, rated current, maximum power and so on. These parameters are the basis for selecting fuses, and only by understanding these parameters can a suitable fuse be selected to protect the circuit.
Determine the fuse type
CONQUER film patch fuse has many types, such as fast fusing type, slow fusing type and so on. Different types of fuses have different fusing characteristics and application scenarios. Therefore, the type of fuse required needs to be determined according to the specific needs of the circuit.
Consider the fuse current rating
The rated current of the fuse refers to the maximum current that the fuse can carry continuously under normal working conditions. When selecting a fuse, ensure that the rated current of the fuse is greater than or equal to the maximum operating current of the circuit. At the same time, in order to avoid misblowing the fuse under normal working conditions, it is also necessary to consider a certain safety margin.
Consider the fuse voltage rating
The rated voltage of the fuse refers to the maximum voltage that the fuse can withstand under normal working conditions. When selecting a fuse, ensure that the rated voltage of the fuse is greater than or equal to the maximum operating voltage of the circuit. If the rated voltage of the fuse is too low, it may cause the fuse to burn under normal working conditions, thus losing its protective effect.
Consider the temperature characteristics of the fuse
The temperature characteristics of the fuse refers to the fuse at different temperatures of the fusible characteristics, in the selection of fuses, need to consider the circuit working environment temperature and the temperature characteristics of the fuse itself, if the circuit working environment temperature is higher, need to choose a fuse with a higher temperature bearing capacity; If the operating temperature of the circuit is low, you need to choose a fuse with a lower temperature coefficient.
